Hi,
Try the following:
Turn on the laptop and when it boots into Windows, force turn it off by holding the Power button until it completely shuts down.
Do this 3 times in a row i.e start > boot > turn off > start > boot > turn off >start > boot etc.
On the 3rd attempt it should boot into the Windows Recovery Environment menus.
When in the menus select ''Troubleshooting > Startup Settings > Advanced > Startup repair'' and follow the prompts.
If that doesn’t work try ''Troubleshooting > Startup Settings > Advanced > System Restore'' or ''System Image Recovery'' (if you have a restore point set or system image that is).
''Do not'' select ''Reset this PC''. If you choose a wrong option after this you may lose all your data as Windows will be reinstalled.
